This is a contemporary table lamp executed in the Mission or Arts and Crafts revival style. The piece features a conical shade constructed from amber-colored mineral mica panels, which are secured by an oil-rubbed bronze or patinated copper frame with decorative rivet details. The base is crafted from heavy-gauge hammered metal, likely copper or brass with a dark chemical patina, exhibiting a distinctive mottled texture characteristic of hand-wrought metalwork. It features a flared trumpet-style neck that transitions into a wide, bulbous foot. The lamp is equipped with a dual-socket configuration, each controlled by an independent ball-chain pull switch with decorative acorn-shaped finials. The hardware includes two curved structural arms that support the shade from beneath. The overall condition appears excellent with no visible tears to the mica or significant dents to the metalwork. The finish shows a deliberate, uniform oxidation intended to simulate an antique appearance. The craftsmanship suggests a high-quality modern reproduction inspired by the designs of Dirk Van Erp or the Stickley brothers, dating most likely to the late 20th or early 21st century.

Based on my visual examination, I have assessed this Arts and Crafts style table lamp. The piece displays the hallmark characteristics of a high-quality contemporary revival, specifically referencing the iconic 'warty' copper work of Dirk Van Erp. The hammered texture is consistent and the dual-socket configuration with acorn finials suggests a production date within the last 20 to 30 years rather than the early 20th century. The condition appears to be excellent, with the amber mica panels showing no signs of flaking or transparency issues, and the patination remains uniform across the base and frame. Market demand for Mission-style lighting remains steady, particularly for well-constructed reproductions that offer the aesthetic of the American Craftsman movement without the $10,000+ price tag of period originals. Comparables for similar high-end contemporary makers, such as Mica Lamp Co. or Arroyo Craftsman, typically hammer between $500 and $1,200 depending on size and provenance. The lack of a visible maker’s mark or stamp on the underside of the base limits a higher valuation. Significant value is derived from the heavy-gauge metalwork and the integrity of the mica. Please note that this appraisal is based on image analysis; a physical inspection is required to verify the specific metal alloy, check for internal electrical safety, and identify any stamped trademarks. Documentation of purchase or a manufacturer's label would be necessary for a definitive attribution to a specific modern forge.
